My invention relates to certain new and use ful improvements in the class of selfbinding attachments for reapin g-machines using twine or cord for bands; and the invention consists in the novel construction, combination, and

arrangement of parts, all as will be hereinafter fully described, and specifically pointed out in the claims. T

To enable others skilled in the art to which my invention is most nearly connected to make and use the same, I will now proceed to describe its construction and operation.

In the drawings, A represents a table to be bolted to the rear end or any other convenient point-of a reaping-machine.

B represents a chain-wheel loosely mounted on ashaft, I), passing through front end of table A, and connected to and operated from a chainwheel on reaping-machine by an endless chain or other equivalent device.

The self-bindin g attachment is put into gear with the reaping-m achine through the medium of clutch mechanism composed of a pivoted shifter, D, having a foot, d, adapted to engage with a stud, E, on the endless chain F, and a spanner, Gr, engaging with a groove, H, in the clutch that engages with the Wheel B, said shifter D being provided with a projecting arm, O, having a cord, a, connected thereto for operating the shifter.

By pulling on the cord a the shifter D is pulled around so that its foot falls off from the stud E on endless chain F, while at the same time the spanner G is actuated so as to force the clutch down until it engages with shaft upon which it is mounted, and thereby communicating motion to the chain-wheel K, rigidly secured upon the lower end of said shaft, through the medium of which motion is communicated to the endless chain F passing around said wheel K and a similar wheel, K, mounted on a shaft near the center of the table.

L represents a rod having one end connected to the endless .chain F and its other end pivoted to a bar, M, of the carriage, upon which is mounted the tying mechanism, and through the medium of which said carriage with the tying mechanism is reciprocated under the table A.

The carriage is connected to the under side of table by a bar, m, above the table, to which it is secured, said bar 122 working in a groove in the table as the carriage is reciprocated under it.

I represents a band-carryin g arm, provided with a bobbin,J, containing, the twine, said arm being pivoted to an arm, 0, rigidly connected to and moving with the carriage. The arm I is provided with a foot, P, which moves over a spring-track, It, mounted upon and at one edge of the table, said track being provided with front and rearinclined grooves, S and Q, through which the foot of the arm I passes in its forward and backward movement, and engaging with a stud or foot, U, projecting from the table at the lower end of the slot Q, for a purpose to be hereinafter described.

W represents a spirally-grooved mandrel journaled in bearings on the under side of the carriage, and operated through the medium of the forked piece Zengaging with the spiral groove thereof. This mandrel is composed of the two parts 10 w, the part to being provided the collar B of the portion to.

with a curved drojectin g j aw, 20 and the part 7.0 with a similar jaw, 20 forming a hook, V, at the front end of the, mandrel when said parts are connected together. Theportion w is also provided with a collar, 13, surrounding the portion to, and said collaris provided with a slot, 0, through which passes a lug, d, on end of the stationary bar D.

The sliding bar M of the carriage is provided with a stud, E, which engages with a shoulder on lever F for thepurpose of pressing the mandrel forward to open the jaws of the hook V, so that the band can pass between them.

G represents a coiled spring surrounding the mandrel between the projecting pin o and This spring is for the purpose of forcing the portion w of the mandrel with its hook 10 forward, for a purpose hereinafter referred to.

J represents a hook with its shank working in a groovein the side of the forward journalbox of the mandrel, for the purpose of retaining the free end of the band while it is carried against and around the sheaf, and also for the purpose of griping the hand between it and the bar D and cutting the band off by a shear cut against the knife 0. This hook is operated through the medium of the sliding bar M, a stud, H, on the shank of the hoolg engaging with a notch, 1, on the sliding bar as it moves forward, thus carrying the hook forward and releasing the band until a stud, K, on the inner side of the shank of the hook strikes an inclined shoulder, L, on the journal-box of the mandrel, which raises the hook so that thestud H is thrown out of engagement with the sliding bar, when the hook is returned to its original position through the medium of the spring M and connecting-rod N, which movement of said hook gripes the I hand between it and the plate D and shears it off against the knife 0.

Yrepresents a notch on the table, with which a catch, X, on the carriage engages for the purpose of locking the carriage when it is at the position shown in Fig. 14, and also releasing the slidingtbar M, which, in its further movement backward and return movement forward, operates the mandrel and the other parts of the tying mechanism, as will be more fully referred to in the description of the operation of the machine.

1? represents a groove extending nearly around the front portion of the mandrel, and

in which a stud, a, on the carriage projects, so

that in the revolution of the mandrelsaid stud forces the mandrel downward when it comes in contact with the portion, at, not grooved, all

from the front end of mandrel.

the hand held by the retaining-hook J against the bar D, and a sheaf thrown across the front portion of the table A by the raking-0d arm of the reaper, the binding attachment is thrown into gear with the reaper, as before described, so that the carriage is caused to move forward in the direction indicated by the arrow in Fig. 4c, and the foot P, traveling up the inclined groove Q, raises the arm above the table, in which position it is held. While the carriage is moving forward the sheaf is collected against the binding cord or band N, the foot of the band-carrying arm traveling over the top of the track until it reaches the forward inclined groove, S, into which it falls. The motion being new reversed, said foot travels down the inclined groove S, which forces the front end, T, of the band-carrying arm down through the opening tin the table A, carrying the band around the sheaf, said foot traveling along the outer side of track as the carriage moves backward until it comes in contact with the foot U, when the track springs out ready for the next forward motion of the carriage, with the foot P resting in the lower end of theinclined groo \Vhen the front end of the band-carryin arm passes down through the table, carryiiig with it the binding cord or band, it descends through the notch-formed lug of the hook V, projecting The carriage having then moved to the rear end of the table, the catch X on the carriage falls into the notch Y in the table, thus locking the carriage and releasing the sliding bar M, which is moved farther backward through the medium of the chain. F and rod L, and as said bar travels backward the forked piece Z, engaging with the spiral groove in mandrel, causesit to be moved backward until the slot G in the collar B passes the lug d on end of bar D, which movement of the mandrel causes the hookV to catch and draw the band the thickness of said hook inside of the hollow mandrel before it starts to revolve, which backward movementof the hook forms half of the tying-loop. The mandrel and hook are now caused to make about three-fourths of a revolution, both parts of the band passing outside of the hook when they commence to cross each other. At this stage of the operation the stud E on sliding bar M comes in contact with shoulder on lever F, pressing twisted mandrel forward and opening the jaws of the hook, which allows both ends of the band to pass between them. The slot 0 in the collar B being new opposite the stud d on bar 1), the coiled spring G forces said collar with the upper jaw, 20 forward, thus griping the two ends of the band between the jaws.

moving farther forward, the stud H drops into notch I on sliding bar, which carries the curved retaining-hook J forward, releasing the end of the band until the inner stud, K, of the shank of the hook J strikes an inclined shoulder, L, throwing the stud H out of engagement with the sliding bar, which permits The sliding bar M w and rod N, to be quickly drawn back,

the hook J, through the medium of spring M griping the hand between it and the bar D and shearing it off against the knife 0', leaving the free end of the band from the bobbin held by the retaining-hook against the bar D to be carried around the next gavel in the manner above described.

The forward. motion of the sliding bar above referred to also reverses the motion of the mandrel and hook V, so that the two ends of the hand held by the jaws of the hook are drawn through the loop formed around the hook, which slips off of the tapering hook in completing the reverse movement, the stud a on the under side of carriage working in the eccentric groove P, and at the point a forces the hook and all its parts downward, which movement draws the knot tight. The forked piece Z, then pressing against the shoulder R on twisted mandrel, opens the jaws of the hook, permitting the band to fall out, thus completing the tying operation. The stud E on chain F then comes under the foot of the shifter D, lifting the clutch H, and thus throwing the chain-wheel 13 out of gear, when the apparatus stands still until the next gavel is collected and thrown onto the table, when said wheel B is again thrown into gear through the medium of the shifter D and operatinglever and cord 0 c, and the above operation repeated.

It will be observed that I employ but one revolving mandrel carried in a hollow bearing, and by its own revolution it winds the cord around both ends of the tying-hook, and when about three-fourths of a revolution is made the jaws of the hook open and clamp between them the ends of the band. The ends are then cut off, when the mandrel is revolved in the reverse direction, allowing the loop of cord to slip off of the hook, retaining the two ends in its gripe, and the eccentric groove in the collar of the mandrel standing against the stud on the under side of carriage forces the end of the mandrel away from the carriage, thus drawing the knot tight.

I am aware that a hollow hooked cylinder or mandrel having a stationary inside inandrel in which works a smaller mandrel provided with a hook is old, and such I do not wish to be understoodas claiming as my invention, it differing from my invention both in construction and operation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a selt binding attachment for reapingmachines, the combination, with the shaft Z), chain-wheel B, loosely mounted thereon, and grooved clutch H, of the pivoted shifter D, provided with a spanner, G, and foot cl, and the endless chain F, provided with a stud, E, with which the foot of the shifter engages,
